First hard evidence found of a lake on Mars

Where there is Water , there is Life !

WASHINGTON (Reuters) - A long, deep canyon and the remains of beaches are perhaps the clearest evidence yet of a standing lake on the surface of Mars -- one that apparently contained water when the planet was supposed to have already dried up, scientists said on Wednesday.

Images from a camera called the High Resolution Imaging Science Experiment aboard the Mars Reconnaissance Orbiter indicate water carved a 30-mile-(50-km-)long canyon, a team at the University of Colorado at Boulder reported.

It would have covered 80 square miles (200 sq km) and been up to 1,500 feet deep, the researchers wrote in the journal Geophysical Research Letters.

There is now no dispute that water exists on the surface or Mars -- robot explorers have found ice. There is also evidence that water may still seep to the surface from underground, although it quickly disappears in the cold, thin atmosphere of the red planet.
